SPECIFICATION forming part of Letters Patent No. 696,679, dated April 1,1902. Application filed January 21, 1902. Serial No. 901633. (No model.)

To aZZ whom it may concern.-

Be it known that we, GEORGE B. HOWARD and J AOOB LANGHART, J r.,citizens of the United States of America, residing at McKeesport, in thecounty of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in Wrenches, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inspanner-wrenches, and relates more particularly to combinationwrencheswherein a sliding-jaw wrench and spanner-wrench are combined.

Although the present invention is shown and described as cooperatingwith a slidingjaw wrench, the principal features of the invention solelyrelate to the spanner-wrench, and the sliding-j aw wrench may bedispensed with, if desired.

The object of the present invention is to provide novel means wherebythe adjustment of the spanner-wrench is obtained which will permit thewrench to grasp all sizes of tubing, bolts, and nuts.

Our invention further-aims to provide a chain that will be partiallyinclosed in a handle or may be adjusted to an extent to grasp all sizesof couplings and the like; furthermore, to provide an arm that whenadjusted to its proper position will form a further fulcrum-point of thewrench.

Our invention still further contemplates to provide a screw-driverattachment that may be conveniently used in connection with a wrenchwhen desired.

Another object of the present invention is to provide a wrench that maybe extremely simple in construction, strong, durable, comparativelyinexpensive to manufacture, and highly efficient in its use.

l/Vith the above and other objects in view the invention consists in'thenovel combination and arrangement of parts to be hereinafter more fullydescribed, and specifically pointed out in the claims.

In describing the invention in detail reference is had to theaccompanying drawings, formingapart of this specification,and whereinlike numerals of reference indicate like parts throughout the severalviews,in which- Figure l is a side elevation of our improved wrench.Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a sideelevation of the wrench when in use. Fig. 4 is a similar view showingthe adjustment of the fulcrum-arm as it appears when applied inposition.

In the drawings the reference-numeral 1 indicates the handle carryingthe stationary jaw 2, and 3 represents a recess formed in the upper faceof the handle.

The sliding jaw 4. is of the ordinary construction, in which is securedthe collar 5, carrying a worm-screw 6, said worm-screw 6 operating in aworm-rack 7, formed on the lower face of the handle. Through the upperface of the sliding jaw i is formed an aperture 8, through which extendsthe lug 9, carried by the screw-driver 10, the latterbeing engaged onits under face by the flat spring 11, which serves to normally press thelug 9 into the opening 8. At the other end of the screw-driver 10 issecured a chain composed of a number of links 12, which are pivotallysecured together, said chain extending through the recess 14, formed inthe end of the handle. This chain 12 carries on its free enda lug 15. Arecess 16 is also formed in the handle 1, in said recess being pivotallysecured at 17 a spring-pressed fulcrurn-arm 18, carrying teeth 19 andretained in position by means of a spring 20, secured in the bodyportion of the handle. In the said fulcrum-arm 18 are formed recesses 21and 22, which are adapted to receive the lug 15 of the chain when thefulcrum-arm is used;

but when the fulcrum-arm is not in use the lug 5 may be secured in therecess 23, formed in the body portion of the handle, or the lug 15 mayengage the opening 2 1, formed in the sleeve 25. The lower end of thehandle, near the end thereof, is curved, as shown at 26, to

receive the sleeve, nut, or other object to which the wrench is applied.

The operation of our improved wrench is as follows: When it is desiredto lengthen or shorten the chain to grasp an object, the sleeve 6 isoperated, thereby imparting the usual movement to the sliding jaw towhich the chain is attached, and by operating the jaw toward thestationary jaw the chain will be shortened, and the reverse movementwill serve to lengthen the chain extending through maythen be placedeither in the recess 21 or 22. When it is desired to use thescrewdriver, the lug 9 is pressed downwardly until the upper face of thelug is in alinement with the under side of the slidingjaw. Then byoperating the jaw the screw-driver attachment is released and the samemay be extended to the upright position through the opening formed inthe handle. The jaw is then tightened until the lower end of thescrew-driver is engaged and firmly held in the desired position.

The many advantages obtained by the use of our improved device will bereadily apparent from the foregoing description, taken in connectionwith the accompanying drawings.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of our invention.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. A chain spanner attached to the movable jaw of a wrench and operatingin a groove on the upper face of the handle thereof with overlappingflanges carried by the handle for securing said chain in position,substantially as described.

2. An adjustable chain spanner comprising a chain carrying a hooksecured to the movable jaw of a wrench, the handle of said wrench on itsrear end being arc-shaped with the upper face of the handle having agroove and overlapping flanges for securing said chain.

in position, substantially as described.

3. An adjustable chain spanner comprising a chain carrying a hooksecured to the movable jaw of a wrench, the handle of said wrench on itsrear end being arc-shaped with the upper face of the handle having agroove and overlapping flanges for securing said chain in position, andafulcrum-arm secured in the handle, substantially as described.

4:. An adjustable chain spanner comprising a chain carrying a hooksecured to the movable jaw of a wrench, the handle of said wrench on itsrear end being arc-shaped with the upper face of the handle having agroove and overlapping flanges for securing said chain in position, anda spring-pressed fulcrum-arm secured in the handle, substantially asdescribed.

5. An adjustable chain spanner comprising achain carrying'a hook securedto the movable jaw of a wrench, the handle of said wrench on its rearend being arc-shaped with the upper face of the handle having a grooveand overlapping flanges for securing said chain in position, and aspring-pressed fulcrum-arm secured in the handle andhaving openingsformed therein to receive the end of the said chain, substantially asdescribed.

In testimony whereof we affix our signatures in the presence of twowitnesses.
